So far so good after three days of operation.  Cools well, reasonably quiet. In attaching the hose connectors to each end of the hoses, follow the instructions to pull out about six inches of hose before screwing it into the connector. The instruction to turn clockwise is less important than checking to see that the hose is going in the direction that will catch on the threads of the connector. Attach the two round fixtures to the window panel with the eight available screws before you attach the connectors to the panel. Do not attach the connectors to the window panel before screwing the hoses into the connectors.
